ABSTRACT

OBJECTIVES: This study was conducted to analyze the effect that oral health literacy of adults has on perceived oral health state and to identify the factors that affect perceived oral health status. METHODS: A self-administered questionnaire survey was distributed to 554 adults who lived in the Daegu or Gyeongbuk areas and visited dental institutions located in the Daegu area. For adults who were 60 years old or older, direct interviews were conducted. Statistical analysis was performed with t-tests, analysis of variance, and multiple regression using SPSS RESULTS: Between oral health literacy and perceived oral health status, a significant positive correlation was revealed (r=0.142, P<0.01). A significant positive correlation was revealed between oral health literacy and knowledge (r=0.397, P<0.01). A significant but weakly positive correlation was revealed between oral health knowledge and perceived oral health status (r=0.086, P<0.05). To identify factors affecting perceived oral health status, multiple regression analysis was conducted, and the result showed that oral health literacy was a statistically significant factor (β=0.105, p<0.05). Among general characteristics, age was a statistically significant negatively affecting factor, as it showed a negative relationship with perceived oral health status (β=−0.140, P=0.001, adjusted R2=0.049). CONCLUSIONS: When these study results are taken into consideration, oral health literacy is a factor affecting perceived oral health status, and as such, oral health literacy of the research targets should be taken into consideration when implementing oral health education to promote oral health.

ABSTRACT

PURPOSE: Proliferation marker Ki-67 is widely used in cancer prognosis prediction. We tried to investigate the role of Ki-67 as a prognostic factor in stomach cancer after surgery in this study. METHODS: We retrospectively evaluated 251 patients who underwent curative resection for gastric cancer from 2010 to 2015. In pathologic examination, Ki-67 labeling index was defined as the percentage of Ki-67 antigen positive cells. Prognostic significance of Ki-67 for gastric cancer was evaluated. Disease-free survival (DFS) was assessed as a primary end-point. RESULTS: The median follow-up period was 28.0 months. Thirty-one patients (12.4%) showed Ki-67 labeling index (LI) lower than 25%. Sixty-eight patients (26.6%) showed recurrence during follow-up period. Recurrence was associated with Ki-67 LI level (≤25%, P = 0.016), and lymph node metastasis status (P = 0.002). High Ki-67 LI level (>25%) was also related to p53 positivity (P < 0.001) and poorly cohesive type (P = 0.002). The 3-year DFS was 69.4%. Low Ki-67 LI level (≤25%) was related with low DFS (47.6% vs. 72.6%, P = 0.016). T stage (P < 0.001), N stage (P = 0.006), lymphovascular invasion (P = 0.010), and neuronal invasion (P = 0.001) also affected the DFS. In addition, T stage (P = 0.03) and Ki-67 LI (P = 0.035) were independent prognostic factors for DFS. In patients treated with adjuvant chemotherapy (n = 239, 93.4%), low Ki-67 (≤25%) was a poor prognostic factor for DFS (P = 0.013). CONCLUSION: Low Ki-67 LI predicts high rate of progression and low DFS of stomach cancer. Ki-67 LI can be a predictive marker in resected stomach cancer treated with surgery and adjuvant chemotherapy.

ABSTRACT

PURPOSE: This study was conducted to discover the clinical factors that can predict pathologically complete remission (pCR) after neoadjuvant chemoradiotherapy (CRT), so that those factors may help in deciding on a treatment program for patients with locally advanced rectal cancer. METHODS: A total of 137 patients with locally advanced rectal cancer were retrospectively enrolled in this study, and data were collected retrospectively. The patients had undergone a total mesorectal excision after neoadjuvant CRT. Histologic response was categorized as pCR vs. non-pCR. The tumor area was defined as (tumor length) × (maximum tumor depth). The difference in tumor area was defined as pre-CRT tumor area – post-CRT tumor area. Univariate and multivariate logistic regression analyses were conducted to find the factors affecting pCR. A P-value < 0.05 was considered significant. RESULTS: Twenty-three patients (16.8%) achieved pCR. On the univariate analysis, endoscopic tumor circumferential rate <50%, low pre-CRT T & N stage, low post-CRT T & N stage, small pretreatment tumor area, and large difference in tumor area before and after neoadjuvant CRT were predictive factors of pCR. A multivariate analysis found that only the difference in tumor area before and after neoadjuvant CRT was an independent predictor of pCR (P < 0.001). CONCLUSION: The difference in tumor area, as determined using radiologic tools, before and after neoadjuvant CRT may be important predictor of pCR. This clinical factor may help surgeons to determine which patients who received neoadjuvant CRT for locally advanced rectal cancer should undergo surgery.

ABSTRACT

The prognosis associated with brain metastasis arising from breast cancer is very poor. Eribulin is a microtubule dynamic inhibitor synthesized from halichondrin B, a natural marine product. In a phase III study (EMBRACE), eribulin improved overall survival in patients with heavily pretreated metastatic breast cancers. However, these studies included few patients with brain metastases. Metastatic brain tumors (MBT) were detected during first-line palliative chemotherapy in a 43-year-old woman with breast cancer metastasis to the lung and mediastinal nodes; the genetic subtype was luminal B-like human epidermal growth factor receptor 2 (HER2)-negative. Whole brain radiotherapy (WBRT) followed by eribulin treatment continuously decreased the size, and induced regression, of the MBT with systemic disease stability for 12 months. Another 48-year-old woman with metastatic breast cancer (HER2+ subtype) presented with MBT. Following surgical resection of the tumor, eribulin with concurrent WBRT showed regression of the MBT without systemic progression for 18 months.

ABSTRACT

PURPOSE: The purpose of this study was to identify the excision repair cross-complementation group 1 (ERCC1) as a predictive marker for FOLFOX adjuvant chemotherapy in stages II and III colon cancer patients. METHODS: A total of 166 high risk stages II and III colon cancer patients were retrospectively enrolled in this study, and data were collected prospectively. They underwent a curative resection followed by FOLFOX4 adjuvant chemotherapy. We analyzed ERCC1 expression in the primary colon tumor by using immunohistochemical staining. The oncological outcomes included the 5-year disease-free survival (DFS) rate. The DFS was analyzed by using the Kaplan-Meier method with the log-rank test. A Cox proportional hazard model was used for the prognostic analysis. RESULTS: ERCC1-positive expression was statistically significant in the older patients (P = 0.032). In the multivariate analysis, the prognostic factors for DFS were female sex (P = 0.016), N stage (P = 0.009), and postoperative carcinoembryonic antigen level (P = 0.001), but ERCC1 expression was not a statistically significant prognostic factor for DFS in the univariate analysis (P = 0.397). The 5-year DFS rate was not significantly associated with the ERCC1 expression in all patients (P = 0.396) or with stage III disease (P = 0.582). CONCLUSION: We found that ERCC1 expression was not significantly correlated with the 5-year DFS as reflected by the oncologic outcomes in patients with high-risk stages II and III colon cancer treated with FOLFOX adjuvant chemotherapy.

ABSTRACT

PURPOSE: Prostaglandin E2 (PGE2) is a contributory carcinogen in gastric adenocarcinoma. 15-Hydroxyprostaglandin dehydrogenase (15-PGDH) catabolizes PGE2 by oxidizing its 15(s)-hydroxy group. The aim of this study was to investigate the expression of 15-PGDH in gastric adenocarcinoma tissue and the relationship between 15-PGDH expression and clinicopathologic features of gastric adenocarcinoma. METHODS: Ninety-nine patients who underwent surgical resection for gastric adenocarcinoma between January 2007 and December 2007 were enrolled and evaluated retrospectively. RESULTS: In 62 patients (62.6%), 15-PGDH expression was lower in gastric adenocarcinoma tissue than in nonneoplastic tissue. Regarding the relationship between 15-PGDH expression and clinicopathological features, 15-PGDH expression was significantly lower in tissues with poor differentiation (P = 0.002), advanced T stage (P = 0.0319), a higher number of lymph node metastases (P = 0.045), lymphatic invasion (P = 0.031), and vascular invasion (P = 0.036). CONCLUSION: 15-PGDH expression was associated with a subset of clinicopathologic features such as differentiation grade, T stage, lymphatic invasion, and vascular invasion.

ABSTRACT

PURPOSE: Hashimoto's thyroiditis (HT) is an important cause of hypothyroidism caused by autoimmune chronic lymphocytic thyroiditis. In order to attain a better understanding for use in treatment of papillary thyroid carcinoma (PTC) coexisting with HT, we conducted an analysis of the clinicopathologic features, as well as the importance of HT as a prognostic factor. METHODS: In this retrospective study, we analyzed 341 patients who were histopathologically diagnosed with PTC following surgery. RESULTS: PTC coexisting with HT was observed in 19.6% (67 patients) of all PTC patients. A statistically significant gender difference was observed in the group with HT (two male vs. 65 female), with a higher positive rate of anti-thyroglobulin antibody and smaller tumor size, compared to the PTC group without HT. When tumor size increased, a lower coexistence rate of HT was observed. No significant differences were observed in multifocality, cervical lymph node (LN) metastasis, coexistence of benign nodule, and extent of LN dissection. However, frequency of extrathyroidal extension was significantly lower and total thyroidectomy rate was higher in the group with HT. TNM stage and AMES stage were similar in both groups; frequency of high MACIS score showed a significant decrease in the group with HT. The recurrence rate and disease- free survival in patients with PTC were not significantly affected by coexistence of HT. CONCLUSION: We found a significant relationship with gender, extrathyroidal extension, and tumor size in PTC coexisting with HT. However, no significant differences in recurrence rate and disease-free survival were observed between groups. Therefore, coexistence in PTC could not be applicable as a prognostic factor of PTC.

ABSTRACT

PURPOSE: The serum level of carcinoembryonic antigen (CEA) is a clinical prognostic factor in the follow-up evaluation of patients with colon cancer. We aimed to evaluate the prognostic significance of the rate of decrease of the perioperative serum CEA level in patients with colon cancer after a curative resection. METHODS: A total of 605 patients who underwent a curative resection for colon cancer between January 2000 and December 2007 were enrolled retrospectively. The rate of decrease was calculated using the following equation: ([preoperative CEA - postoperative CEA]/[preoperative CEA] x100). RESULTS: In the group with a preoperative serum CEA level of >5 ng/mL, the normalized group with a postoperative serum CEA level of 5 ng/mL, the prognostic factors for the OS and the DFS were the cutoff value (P < 0.0001) and the pN stage (P < 0.0001). CONCLUSION: A rate of decrease of more than 50% in the perioperative serum CEA level, as well as the normalization of the postoperative serum CEA level, may be useful factors for determining a prognosis for colon cancer patients with high preoperative CEA levels.

ABSTRACT

BACKGROUND: Carcinoma-associated fibroblasts (CAFs) contribute to carcinogenesis and cancer progression, although their origin and role remain unclear. We recently identified and investigated the in situ identity and implications of gastric submucosa-resident mesenchymal stem cells (GS-MSCs) in the progression of gastric carcinogenesis. METHODS: We isolated GS-MSCs from gastric submucosa using hydrogel-supported organ culture and defined their identity. Isolated cells were assessed in vitro by immunophenotype and mesengenic multipotency. Reciprocal interactions between GS-MSCs and gastric cancer cells were evaluated. To determine the role of GS-MSCs, xenografts were constructed of gastric cancer cells admixed with or without GS-MSCs. RESULTS: Isolated cells fulfilled MSCs requirements in regard to plastic adherence, stromal cell immunophenotype, and multipotency. We demonstrated a paracrine loop that gastric cancer cells enhanced the migration, proliferation, and differentiation of GS-MSCs; additionally, GS-MSCs promoted the proliferation of gastric cancer cell in vitro. Xenograft experiments showed that GS-MSCs significantly promoted cancer growth and angiogenesis. GS-MSCs that integrated into gastric cancer became not only CAFs but also rarely endothelial cells which contributed to the formation of cellular and vascular cancer stroma. CONCLUSIONS: Endogenous GS-MSCs play an important role in gastric cancer progression.

ABSTRACT

PURPOSE: To maintain the patient's quality of life, surgeons strive to preserve the sphincter during rectal cancer surgery. This study evaluated the oncologic safety of a sphincter-saving resection with a distal resection margin (DRM) 1 cm), the 5-year cancer-specific survival rates were 81.57% and 80.03% (P = 0.8543), the 5-year local recurrence rates were 6.69% and 9.52% (P = 0.3981), and the 5-year systemic recurrence rates were 19.46% and 23.11% (P = 0.5750), respectively. CONCLUSION: This study showed that the close DRM itself should not be a contraindication for a sphincter-saving resection for T3 mid- or low-rectal cancer without radiotherapy. However, a prospective randomized controlled trial including the effect of adjuvant therapy will be needed.

ABSTRACT

PURPOSE: This experimental study verified the effect of adipose-tissue-derived stem cells (ASCs) on the healing of ischemic colonic anastomoses in rats. METHODS: ASCs were isolated from the subcutaneous fat tissue of rats and identified as mesenchymal stem cells by identification of different potentials. An animal model of colonic ischemic anastomosis was induced by modifying Nagahata's method. Sixty male Sprague-Dawley rats (10-week-old, 370 +/- 50 g) were divided into two groups (n = 30 each): a control group in which the anastomosis was sutured in a single layer with 6-0 polypropylene without any treatment and an ASCtreated group (ASC group) in which the anastomosis was sutured as in the control group, but then ASCs were locally transplanted into the bowel wall around the anastomosis. The rats were sacrificed on postoperative day 7. Healing of the anastomoses was assessed by measuring loss of body weight, wound infection, anastomotic leakage, mortality, adhesion formation, ileus, anastomotic stricture, anastomotic bursting pressure, histopathological features, and microvascular density. RESULTS: No differences in wound infection, anastomotic leakage, or mortality between the two groups were observed. The ASC group had significantly more favorable anastomotic healing, including less body weight lost, less ileus, and fewer ulcers and strictures, than the control group. ASCs augmented bursting pressure and collagen deposition. The histopathological features were significantly more favorable in the ASC group, and microvascular density was significantly higher than it was in the control group. CONCLUSION: Locally-transplanted ASCs enhanced healing of ischemic colonic anastomoses by increasing angiogenesis. ASCs could be a novel strategy for accelerating healing of colonic ischemic risk anastomoses.

ABSTRACT

PURPOSE: The aim of this study was to analyze the oncologic outcomes and the risk factors for recurrence after a tumor-specific mesorectal excision (TSME) of resectable rectal cancer in a single institution. METHODS: A total of 782 patients who underwent a TSME for resectable rectal cancer between February 1995 and December 2005 were enrolled retrospectively. Oncologic outcomes included 5-year cancer-specific survival and its affecting factors, as well as risk factors for local and systemic recurrence. RESULTS: The 5-year cancer-specific survival rate was 77.53% with a mean follow-up period of 61 +/- 31 months. The overall local and systemic recurrence rates were 9.2% and 21.1%, respectively. The risk factors for local recurrence were pN stage (P = 0.015), positive distal resection margin, and positive circumferential resection margin (P < 0.001). The risk factors for systemic recurrence were pN stage (P < 0.001) and preoperative carcinoembryonic antigen level (P = 0.005). The prognostic factors for cancer-specific survival were pT stage (P < 0.001), pN stage (P < 0.001), positive distal resection margin (P = 0.005), and positive circumferential resection margin (P = 0.016). CONCLUSION: The oncologic outcomes in our institution after a TSME for patients with resectable rectal cancer were similar to those reported in other recent studies, and we established the risk factors that could be crucial for the planning of treatment and follow-up.

ABSTRACT

PURPOSE: Extrathyroidal extension (ETE) is a risk factor for the recurrence of a papillary thyroid carcinoma (PTC). In the TNM 6(th) classification system, an extrathyroidal invasion of a differentiated thyroid carcinoma has been classified as T3 (minimal invasion), T4a (extended invasion), and T4b (more extensive unresectable invasion) according to tumor invasion. We investigated the clinicopathologic characteristics, recurrence, and disease-free survival (DFS) of minimal ETE (mETE). METHODS: We retrospectively evaluated 332 patients who underwent a thyroidectomy for PTC from January 2005 to December 2006. RESULTS: Of the 332 patients, 103 (31.0%) were found to have a PTC with mETE and 229 (69.0%) patients had a PTC without mETE. In PTC, mETE was related to gender, tumor size, multifocality, Lymph node (LN) metastasis, underlying Hashimoto's thyroiditis, and surgery. But there is no significant difference in age, recurrence, and LN metastasis between the mETE and No mETE groups. Multivariate analysis demonstrated that LN metastasis (odds ratio=2.273; 95% confidence interval 1.280~4.037) was recognized as an independent factor for mETE (P=0.005). Disease-free survival was not significantly different between patients with and without mETE (P=0.153). We analyzed the effect of LN metastasis in groups with and without mETE. Based on the presence or absence of LN metastasis, disease-free survival (DFS) rates between each group showed no significant differences. CONCLUSION: Minimal ETE had no impact on DFS in patients with PTC. Therefore, an appropriate surgical approach and postoperative follow-up are required for tumors with mETE.

ABSTRACT

PURPOSE: We wanted to evaluate the clinical and radiographic results of ceramic on ceramic bearing cementless total hip arthroplasty with a minimum of 10-years follow up. MATERIALS AND METHODS: This study was performed on 44 patients and 51 hips, and the patients were recruited among the patients who underwent ceramic-ceramic type cementless total hip arthroplasty from August 1998 to February 2000 and they were available for 10-years or longer follow up. The gender ratio was 28 males and 16 females, and the mean age at the time of surgery was 49 years (range: 26~77 years). Regarding the causality of disease, osteonecrosis was noted in 36 cases, degenerative arthritis was noted in 4 cases, acetabular dysplasia was noted in 4 cases and septic or tuberculous hip sequelae was noted in 7 cases. The clinical evaluation was performed according to the Harris hip score, and for the radiological evaluation of the femoral component, we assessed the degree of subsidence and the presence of periprosthetic osteolysis, endosteal new bone formation and cortical hypertrophy, and the final fixation state of the implant. In the cases with an acetabular cup osteoscleostic line in the vicinity of the acetabular cup, endosteal new bone formation, acetabular osteolysis and the vertical migration as well as the horizontal migration of the acetubular cup were assessed. RESULTS: Regarding the clinical outcomes, the Harris hip score was improved from an average 59 points to 93 points at the final follow up. For the radiological results, osteolysis was not detected in the acetabular and femoral components, the subsidence of femoral stem was not beyond 2 mm on average and significant subsidence was not detected. In regard to complications, linear fracture during surgery was noted in 6 cases and postoperative hip dislocation was noted in 1 case. A ceramic head fracture occurred in one case and a ceramic liner fracture occurred in 2 cases. CONCLUSION: This type of articulation is a promising option at a minimum of 10-years follow up of 51 hips that underwent ceramic-ceramic bearing cementless total hip arthroplasty. However, our results demonstrated that surgeons should be aware of the potential risks of ceramic fracture when using ceramic-on-ceramic bearing surfaces. Additional longer-term follow-up is necessary.

ABSTRACT

PURPOSE: This study examined the relationship between the findings of a second-look arthroscopy and clinical results in double bundle anterior cruciate ligament (ACL) reconstruction using hamstring tendons fixed with a Ligament Plate(R). MATERIALS AND METHODS: Twenty eight cases of a double bundle ACL reconstruction using hamstring tendons were retrospectively reviewed. The follow-up period was more than 1 year and all cases were reviewed by second-look arthroscopy. The average follow-up period was 20.6 months (range: 12-34 months). In second-look arthroscopy, the anteromedial (AM) bundle and posterolateral (PL) bundle of the grafts were evaluated based on the tension, rupture and synovial coverage. Clinical evaluation was assessed using the Lysholm score, international knee documentation committee score, Hop test, Lachman test, pivot shift test, KT-2000 arthrometer and anterior drawer stress radiograph using Telos(R) in 30degrees knee flexion. The correlation between the arthroscopic findings of the grafts and the instability tests was evaluated. RESULTS: The AM graft was evaluated as being taut in 89.3% and lax in 10.7%, and the PL graft was assessed as being taut in 71.4% and lax in 28.6% according to the tension. The AM and PL grafts were evaluated as 'no rupture' in 78.6% and 'partial rupture' in 21.4%. There was no 'complete rupture' in any graft. The AM grafts were found to be good in 53.6%, fair in 35.7% and poor in 10.7%; the PL grafts were assessed as good in 50.0%, fair in 28.6% and poor in 21.4% according to the synovial coverage. The AM graft tension showed statistically significant results regarding both the Lachman test (rho=0.743, p<0.001) and degree of rupture (rho=0.438, p=0.020). The PL graft tension showed statistically significant results regarding both the pivot shift test (rho=0.548, p=0.003) and the degree of rupture (rho=0.663, p<0.001). CONCLUSION: Double bundle ACL reconstructions using hamstring tendons show good biological and clinical results. The graft tension and the degree of rupture show a statistically significant relationship to the stability of the reconstructed joint. On the other hand, the synovial coverage did not show a significant result.

ABSTRACT

PURPOSE: Pathogenesis of intraneural ganglion is controversial, however, the synovial theory that the intraarticular region is the origination of disease has come into the spotlight nowadays. But there are a few researches about intraneural ganglion in foot and ankle. We studied 7cases of intraneural ganglion. We are going to prove the synovial theory by indentifying articular branch of intraneural ganglion. MATERIALS AND METHODS: From August 2003 to May 2011, we evaluated 7 ouf of 8 patients diagnosed as a intraneural ganglion in foot and ankle. The gender ratio were 4 male and 3 female, and the mean age at the time of surgery was 52.9 years. Clinically, we checked pre and post operative symptom, muscle tone and whether loss of muscle tone and sensation exists. We analyzed surgical records and preoperative MRI and compared those with intra-operative finding. RESULTS: In MRI analysis of 7cases, the connection around the joints were confirmed, and 1 case was confirmed in the retrospective analysis of MRI. Intraneural ganglions occurred in medial plantar nerve 3 cases, lateral plantar nerve 1 case, superficial peroneal nerve 1 case and sural nerve 1 case. We could not found recurrence during the follow up periods. Most patients relieved pain after operation, but recovery of sensation was unsatisfactory. We could find some cases pathological finding of the nerve intraoperatively, and clinical result of that cases was poor. CONCLUSION: Intraneural ganglion can occur in various parts in foot and ankle. We concluded that the intranneural ganglion originated from joint by identifying the artichlar branch of ganglion. Due to its small size, it is difficult to find articular branch in operation field. But we do our best to find and remove articular branch. Currently, considering the small amount of research in foot and ankle, more research about articular brach is needed.

ABSTRACT

Gallbladder perforation during laparoscopic cholecystectomy (LC) with spillage of bile and gallstones occurs frequently, but clinical sequelae caused by dropped gallstones are uncommon. We present a case of subhepatic and right-back abscess formation due to spilled gallstones occurring two years after LC, which were successfully removed using a percutaneous method as a minimally invasive technique. The patient firstly visited a primary care physician with right-back mass that was increasing in size and becoming symptomatic, then underwent incision and drainage. He was referred to our hospital and the subhepatic and right-back inflammatory mass containing spilled gallstones was revealed by computed tomography. Under fluoroscopic control, a percutaneous drainage catheter was placed within the abscess and pus was aspirated. The spilled gallstones were successfully retrieved with basket forceps, thereafter. The patient was discharged without significant complications on the 9th day after the percutaneous stone removal.

ABSTRACT

PURPOSE: Hepatic resection and liver transplantation are considered a curative treatment for hepatocellular carcinoma (HCC) within the Milan criteria. In this study, we examine the outcome of hepatic resection for HCC within the Milan criteria, and determine the effectiveness of hepatic resection as the primary treatment for HCC within the Milan criteria in Child-Pugh class A. METHODS: 110 patients underwent curative surgical resection for HCC in Child-Pugh class A between August 1991 and June 2008. Fifty-six patients met Milan criteria (Group M) and the remaining 54 did not (Group N). RESULTS: Overall survival rates at 1, 3, and 5 years were 92.6%, 72.5% and 54.6% versus 70.4%, 43.1%, and 28.7% in Group M and Group N, respectively (P=0.0043). The corresponding disease-free survival rates were 81.5%, 69.7%, and 38.2% versus 46.0%, 32.9%, and 26.9% in Group M and Group N (P=0.0012). HCC recurred in 25 patients in Group M (44.6%) and 35 patients in Group N (64.8%)(P=0.034). Outcomes of hepatic resection in Group M were significantly better compared to Group N. CONCLUSION: Hepatic resection can achieve a comparable 5-year overall survival & disease-free survival to that reported for liver transplantation. Hepatic resection should be considered as the standard therapy for HCC within the Milan criteria in Child-Pugh class A patients.

ABSTRACT

Myotonic dystrophy is the most common systemic disease causing myotonia. We report the case of respiratory failure in a patient with myotonic dystrophy after laparoscopic cholecystectomy. We carried out neurologic testing, electromyography and DNA testing in this patient and electromyography in the family of the patient. Through electromyography and DNA testing, this patient was diagnosed with myotonic dystrophy type I. Myotonic dystrophy is characterized by gradual decline of muscle tone and myotonia. It is important that this disease be excluded through preoperative history taking, physical examination and family history taking.
